[AccessD] field cannot be updated...

Hi Bill,
no, it's unique only in people and not in peoplefilms because the most usual 
for a person is to appear more than one time in the same movie (e.g. as 
director and as an actor too)

the weird is that it works for another similar database (for short films) in 
which the relationships are designed exactly the same field by field

people
ID_people --> Auto increment, Primary, Not Null, Unique
person      --> Primary, Not Null, Unique
sex            --> a simple checkbox

peoplefilms
aa_peoplefilms --> Auto increment, Primary, Not Null
ID_films            --> Primary, Not Null
ID_person         --> Primary, Not Null

thank's for your response

Can you make changes BEFORE you add a record? It smells like one of those
not update able query issue that happens when Access can't prove to itself
there could be one and only one record that reults from the join. Which
would be, if you joined on a key that is unique in both tables. Is IDPerson
unique in both tables?

If not, I would be surprised you could update existing records either,
whether the field be aa or sex.
